ISRAEL MARMORSTEIN HENRY STONE, OF NEW YORK, N. Y.

SAFETY-LOCK FOR RIBBONS, BRACELETS, BELTS, AND OTHER SIMILAR ARTICLES.

oi? Hungary, (who has filed his first papers for citizenship of the United States,) have made certain new and useful Improvements in Satetyliocks ior Ribbons, Bracelets, Belts, and other Similar Articles; and we hereby declare the following specification to be a description of the same, reference being had to the accompanying drawings.

This invention relates to a construction of slide and lock which will permit the lengthening of ribbons such. as are used for watch guards and secure the parts at any desired position. It is also adapted for use with belts, bracelets, and other similar arti cles where a ready means of lengthening and shortening is desired.

The object is to provide a safety look at the difi'erent adjustments in length, com bined with ready means of shifting the locking device.

Figure 1 is a view of the lock in position on a strip of braid;

Fig. 2 is a view of the lock separate from the braid;

Fig. 3 is a plan view of the under locking plate;

Fig. l is a separate view of the slideand Fig. 5 is a side elevation oi Fig. 1.

The slide portion A, has three bars a, b, and c leaving two slits through which the braid B or buckle strap will pass. The central bar has two studs, 6, e, projecting from it and these studs have heads slightly larger than the shanks. The slide piece A is curved so the braid will be retarded inpassing through the slots.

C and C form the portion to be secured to'an end of the braid B, and combined with the slide A, secures it at various lengths.

The two plates C, and C are hinged to Specification of Letters Patent.

Application filed February 24, 1919. Serial No. 278,665.

gether at h, and the plate C, is provided with a slot 2', to which an end of the braid is attached.

The plate C, is pierced with the keyhole shaped openings k, k which register in position to fit over the studs 0, e.

The larger part of the openings 70, k is the same size as the head of the studs, the reduced portion of the openings being contracted to the same width as the shanks.

The looking or folding plate G has two circular openings 0, 0, of the size of the heads of the studs 6, 6. These openings are located so that when the studs reach the end of the contracted portion of the keyhole slots and the plate C is folded down the heads of the studs will be received in them.

On the edge of the plate C opposite the hinge is a projecting clasp p, which holds the two plates 0 and Cl, together under ordinary pressure.

When the two plates of the lock are closed with the studs of the slide, in position in the holes of the plate C the ends of the studs are flush with the face of the plate.

lit will be understood that changes of the parts and the number of studs and holes may be made without departing from the spirit of our invention.

Having described our new and improved lock, what we claim as our invention and desire to secure by Letters-Patent is g A slide lock of the class described comprising a slide with two slit openings one on each side of a eentral'bar carrying two headed studs, a hinged securing piece formed of two plates one of which plates is pierced with locking slots to receive and confine the said studs and the other hinged plate with openings adapted to receive and hold the heads of said studs in their locked position, substantially as and for the purposes shown and described.
